DDC-2 Dies

[ziddey]

My ddc 2 <Laing DDC w/ Petra'sTech DDCT-01s Top Combo> die in 4 days
I recive from 28-3-2007 now today it die already .
use for 8-10 hours per day .first time i not have see this topic . I Order & pays already . anyway i read this topic seem 5% die but why happen to me T_T . long way to buy <I live in THAILAND> .

OMG what i have to do .

whack the pump
it should go again

[SiGfever]

If my replacement dies anytime soon I will be going back to my trusty D5 until Laing get get their act together.

50k/hrs MTBF must be a magical time in a land long forgotten. Or was it supposed to be 50hrs MTBF?

So far (knocks on wood) the DDC-2 replacement is chugging along. But I am looking at the Iwaki.

Same here, my replacement DDC has been running fine for a week now (my first one died after 8 days though) *knocks on wood

before I never worried about my pump dying, but now I'm constantly checking my temp sensors...

[shikuva]

first i have to say sorry for my bad English
for me now Petra's send a new DDC2 for me Great work for that point
& also i don't wanna make it die again plane for use fan 120 CM for cool the pump ^ ^ so diffical make the plexi like that don't look nice just try for fit in CM Stacker . Hope fully this way the pump not going to die soon <not cut plexi
for make air flow yet>

Would be interesting for some one to machine an aluminium Commutator housing for them as a heat sink and see what that does?

[Chas_The_Man]

Easier than that would be to externalize the electronics. Thats some cheap nasty stuff in there and it could seriously use some beefing up.

My Laing DDC w/ Petra's DDC-02 Top Combo died overnight during testing for leaks. No leaks found but a burnt smell of plastic in the room. :-(

[septim]

ouch on that.

[Chas_The_Man]

Retierating, cheap nasty stuff.

cleaning the housing may be a good idea, but I never figure out how to take out the impeller???

it just pops out .. it is held in by a magnet

I got new pump today from Petra's <Thank a lot Quoc Ngo> . thinking about bigNG

that's even worse than mine (see post 134 on page 6) mine ran for like a week before it crapped out. but then you're lucky I guess it broke down that fast, nothing more frustrating then having your loop up and running and think it's fine.

[serialk11r]

why arent more people going D5 already??

after seeing this i think i will when i build

DDC+ is a much better pump for watercooling, disregarding the apparently lower reliability.

[sreedx2]

how noisy is the D5 compared to the DDC's ?

also how much of a benefit do you get going with ddc 2 vs D5

First one, I really don't know (I've heard some people say D5 is louder, I've heard some people say DDC is louder), second one, depends. With a very free flowing loop (1 block, 1 rad or something), there shouldn't be too big of a difference. As you start to throw more and more restriction in, the D5 can't keep up, period.

My D5 at max speed 5 was quieter than my DDC2 in its original top. The D5 has much less vibration than the DDC2 so that might explain why.

Funny thing, that... If you check my original pump testing thread, the results that I gathered showed the opposite.

As the pressure drop incurred by the cooling loop increases, the pumps (D5, 50Z, DDC-2) all get closer and closer (as far as flowrate goes). The differences between the pumps are more pronounced with a moderately restrictive loop. Now, I could draw up a spiffy diagram with PQ curves and such to show why this is... but it's late.

[JeffnWV]

well my DDC-2 with PTS top decided to stop last night too after one week of proud daddy WC'ing.

What to do....

I wonder if this will become the longest thread in XS.

[Terryb47]

welcome to the club Jeff

[ign0]

I start to wonder the failure rate... seems too many?

[BigRollTide1]

Dang I got my DDC pump from Petra's with the top last week and won't be building my system until next (not this) weekend at the earliest. Hope my pump lasts.

[JeffnWV]

when I came back home today and turned the pc on (has been off for a few hours) the pump wouldn't come on until I whacked it a few times. So it's not a heat related thing

Good thing I got that training in the Navy or I wouldn't know what to do!

Waiting for PTS to open up and see if I can get any help...
